l AUTOMOBILE i HEATER.

Application filed 'November 17, 1923. Serial No. 675,343.

To .all whom it may concern.:

Be it known that l, LunasV D. Neilson, a citizen of the United States, residing at Coldwater, Ycounty of Branch, VState of h/lich- .igan,` have invented certain new and nseinl lm provements in Automobile Heaters, of which the following is a specification.

This invention relates to improvements in antOmObile heater y The main object of this invention is to provide an improved auton'iobile heater which may be util-ized in connection with a. heatgn'v for the intake .manifold and for heating for the Qar'bureter, which may ,be quickly n applied without disassembling .the parts ofthe automobile to which it is applied.

Further objects, and objects lpertaining 'to details and economies ofconstruction and operation will definitely appear` from .the detailed `description to follow.

I accomplish the objects of my invention by the devices and ymeans described in .the

following specifi-cation. i The invention is clearly .defined and Ypointed aout in the claims.

A structure which Vis a preferred embodiment .of my invention is clearly illustrated in the accompanying drawing forming a. part of this application, .in which:V

Fig l is a side elevation of a structure embodying the features of my invention, the intake and exhaust manifolds and exhaust pipe of an internal combustion engine being indicated by dotted lines and; a portion of the floorboard of the vehicle being shown in order to illustrate the relation of my in proved heater to these parts when installed.

Fig. Il is a plan view of the parts disassembled, the manifold housing being partially broken away.

Fig. III is an inverted view of the register boX and conduit members, the register box being partially broken away.

In the drawing similar reference characters indicate similar parts in all of the views.

Referring to the drawing, 1 represents the footboard of a motor vehicle, 2 the intake manifold and 3 the exhaust manifold thereof. I provide a housing comprising a front side wall section l and a top wall section 5, the top wall section being detachably and adjustably secured by providing it with the slotted lugs 6 engaged by the screws?. The side wall is extended at 8 rearwardlyV beyond the top wall as shown in Fig. II.

The section 4 is provided with a nipple 9 )ipe sho-wn by at its rea-r end adapted .to receive .the .pipe 10 connected to the air inlet of the -carbureteiz, the carbure-ter not being shown.

rThe yrep-gister box 'll has an opening l2 on its under side adapted to engage the exhaust register boaY may be engaged with .the pipe by Aa lateral movement relative thereto. The regster face l-l is detachably secured to *er fl oi; by lmeans of screws 15 engaging the ears on the box. ter box is adapted to be set into the floor* beard l as shown in Fig. I.

The conduit member 17 has telescoping engagement with the front end of the regisdotted vlines .at 13., that is, the

This regis- 1 :ter box and is secured thereto by mea-ns .of

the rivets i8., the rivets :being ,disposed at the upper sides of these members ,-pernintting tecscozping :adjustment betiveenfthe register' honY and the .conduit member..v rllhe Conduit n ein )er `is open .on its under sine so that'it vmay ibe placed at the rear endiof the vexhaust manifold, it having a rear wall t9 depending at the rear ofthe manifold .and a top wall 26) complementing the togp wall 5 yof :the

hou-sing. f

The conduit :inenzber'fhas a slot 21 registering avith .the 'bolt-hole 22 in .the rear 23 on the housing member so that the bolt or screw 241 may be readily engaged with the ear and limited adjustment between the parts permitted to compensate for structural inaccuracies and variations in relation of the fluorboard to other parts.

rlhis arrangement of parts enables their being quickly and easily Yassembled in an automobile by persons not skilled. The parts also have the advantage of being very economical in structure. f 1

Having thus describedmy invention what I claimas new and desire to secure by Letters Patent is:

1. In a structure of the class described, the combination of a housing for the exhaust manifold of an internal combustion engine comprising a top wall and a side wall, the side wall being extended rearwardly beyond the top wall and provided with an inwardly projecting lug having a bolt opening therein, a register boX adapted to be inserted in the footboard of a motor vehicle and havingY an opening in the bottom wall thereof adapted to fit over the exhaust pipe of an internal combustion engine, a conduit member having telescoping engagement with the front end of said register box, connecting rivets for said conduit member and register' box disposed at the top thereof permittting relative tilting adjustment of the parts, said conduit being adapted to overlap the rear end of said side Wall and complement said housing top and having a slot therein registering with said bolt hole in said lug, and a bolt disposed through said slot to engage said lug.

2. In a structure of the class described, the combination of a housing for the exhaust manifold of an internal combustion engine comprising a top wall and a side Wall, the side Wall being extended rearwardly beyond the top wall, a register box adapted to be inserted in the footboard of a motor vehicle and having an opening in the bottom Wall thereof adapted to fit over the exhaust pipe of an internal combustion engine, a conduit member having telescoping engagement With the front end of said register box, connecting rivets for said conduit member and register box disposed at the top of the register box permitting relative tilting adjustnient of the parts, and said conduit being adapted to overlap the rear end of said side Wall and complement said housing top.

In a structure of the elass described, the combination of a housing for the exhaust manifold of an internal combustion engine, a register box adapted to be inserted in the footboard of a motor vehicle and open at the bottom to receive the exhaust pipe of an internal combustion engine When presented laterally thereto, and a conduit member having telesooping engagement With the front end of said registei` box, said register box and conduit member being connected to permit relative tilting adjustment, and said conduit member being detachably connetted to said housing to receive the heated air ther-efroin.

a. ln a structure of the class described, the combination of a housing for the exhaust manifold of an internal combustion engine, said housing comprising a top Wall and a side Wall, the side Wall being extended rearwardly beyond the top Wall, a conduit meniber adapted to overlap the rear end of said housing side Wall and complement the said housing top Wall, means for adjustably seeui'ing said conduit member to said housing, a register box adapted to be inserted in the footboard of a motor vehicle, and connecting pivots for said register box to said conduit member disposed to permit the tilting adjustment of the register box relative to the Conduit member.

5. ln a structure of the class described, the combination of a housing for the exhaust manifold of an internal combustion engine, a register box adapted to be inserted in the footboard of a motor vehicle and having a slot-like opening in the bottom thereof adapted to receive the exhaust pipe of an internal co-ixibustion engine when presented laterally thereto, and a conduit member connecting said housing and register box, said register box being pivotally associated With said conduit member to permit tilting'adjustinent of the register box.

ln Witness whereof, l have hereunto set my hand.

Linvis D. NELSON.
